Blender bottles have become a staple in many kitchens for their convenience and portability. The plastic bottles with flip tops and mixer balls allow you to quickly whip up protein shakes, smoothies, and more to take on-the-go.
But can you microwave these popular blender bottles? Are they microwave safe?
The short answer is yes, you can microwave blender bottles as long as you take the proper precautions. The key is understanding what material your blender bottle is made from and how to microwave it safely.
In this comprehensive guide, we’ll cover everything you need to know about microwaving blender bottles. By the end of this article, you’ll understand exactly how to microwave your blender bottles safely and get the most out of these convenient drink containers.
Benefits of Microwaving Blender Bottles
Why would you want to microwave your blender bottle in the first place? Here are some of the benefits:
- Quick heating: Microwaving is one of the fastest ways to heat up the contents of your blender bottle. This allows you to enjoy warm protein shakes, oatmeal, soups and more.
- Portability: Since blender bottles are designed for portability, microwaving them allows you to prepare foods and drinks at home and take them with you on-the-go.
- Easy cleaning: Microwaving can help loosen stuck-on residue in your blender bottle for easier cleaning. The heat helps dissolve and loosen the gunk.
- Sanitizing: Running your blender bottle through the microwave can help kill bacteria for improved sanitation.
As long as your blender bottle is microwave-safe, warming it up in the microwave can be a convenient way to heat up the contents quickly and safely.
Are Blender Bottles Microwave Safe?
Not all blender bottles are created equal when it comes to microwave safety. The microwave safety of a blender bottle depends on what material it is made from.
Some types of plastic can melt, warp, or release chemicals when microwaved. Metal components like blender balls can also cause arcing and sparks in the microwave.
To identify if your blender bottle is microwave-safe, look at the bottom or packaging and check for any microwave safety labels. The bottle should be clearly marked as “microwave safe.”
If your blender bottle does not have a microwave-safe label, you should not microwave it.
Microwave Safe Blender Bottle Materials
What types of materials are safe for microwaving blender bottles? Here are the most common microwave-safe blender bottle materials:
- Polypropylene (PP) – One of the most popular materials, polypropylene is microwave and dishwasher safe. Polypropylene can safely withstand temperatures up to 212°F before melting.
- Polyethylene (PE) – This includes HDPE (high-density polyethylene) and LDPE (low-density polyethylene). Both are microwave safe but LDPE cannot withstand as high of temperatures.
- Polycarbonate – Shatter-resistant polycarbonate bottles marked “BPA free” are also microwave safe. Avoid older polycarbonate with BPA.
- Glass – Borosilicate glass blender bottles are completely microwave safe. They can withstand rapid heating.
- Silicone – Food-grade silicone components on blender bottles are microwave safe up to about 425°F.
- Stainless Steel – Insulated stainless steel blender bottles without electronic components can be microwaved.
Avoid microwaving blender bottles made from polyvinyl chloride (PVC), polystyrene (PS), acrylonitrile butadiene styrene (ABS), nylon, and polyurethane without checking labels. These may not be microwave safe.
If in doubt, verify the material with the manufacturer before microwaving your blender bottle.
How to Microwave a Blender Bottle
Once you’ve confirmed your blender bottle is microwave-safe, follow these steps to heat it up properly:
- Remove any metal or electronic partsTake off the metal blender ball, electronic mixer, rubber grips, or plastic lids. The metal and electronics can damage the microwave or cause electrical arcing.
- Take out the inner containerIf your blender bottle has a silicone or rubber outer sleeve, remove the inner plastic container before microwaving. The outer sleeves are not microwave safe.
- Fill with your ingredientsAdd the ingredients you want to heat up into the blender bottle. Do not overfill past the max line, usually around 20-25 oz. Leave room for expansion.
- Microwave in short incrementsMicrowave the blender bottle in 30 second bursts, stirring or shaking in between. Go for 1-2 minutes total to evenly heat ingredients.
- Let it stand & shakeWhen done microwaving, let the blender bottle stand for 30 seconds before handling so the contents can settle. Gently swirl or shake to distribute the heat.
- Re-attach parts when cooledBefore drinking, let the blender bottle cool down sufficiently and re-attach the lid, ball, grips, etc. Screw on the lid to avoid spilling.
Following this process will allow you to safely microwave your blender bottle without overheating or damaging it.
Microwave Power Levels
Use lower microwave power levels around 50% when heating blender bottles to avoid hot spots. This allows more even heating. Higher power can lead to boiling or scalding.
Stirring/shaking the bottle every 30 seconds also prevents uneven hot spots. Never microwave a blender bottle over high power continuously in one go.
Microwave Alternatives for Heating Blender Bottles
If you do not have a microwave-safe blender bottle, there are some alternative methods to heat up the contents:
- Stovetop – Heat up a small pot with the contents on the stovetop, then transfer to your blender bottle.
- Hot water bath – Place the sealed blender bottle in a bowl of hot (not boiling) water to gently heat up.
- Instant hot water dispenser – Use your electric kettle or instant hot water tap to heat up water, then combine with your blender bottle ingredients.
- Heating pad – Wrap your sealed blender bottle in a microwave-safe heating pad to slowly warm it up.
- Hot pack – Fill a silicone pack with hot water and place against the blender bottle to transfer warmth.
While not as fast as the microwave, these methods can work if you don’t have a microwave-safe container. Just make sure to heat slowly and gently.
Cleaning Microwaved Blender Bottles
It’s important to properly clean your blender bottle after microwaving it to remove any stuck-on food and kill bacteria.
Here are some tips for cleaning a microwaved blender bottle:
- Rinse with hot water immediately after use to loosen residue
- Use a bottle brush with hot soapy water get into hard-to-reach areas
- Consider using a mild bleach or vinegar solution for sanitization
- Use the dishwasher cleaning cycle if your bottle is dishwasher safe
- Let bottles fully air dry upside down to prevent mold growth
Avoid using abrasive scouring pads or cleaners when cleaning plastic blender bottles as they can scratch the material. Stick to non-abrasive sponges and soft brushes only.
Thorough cleaning after each use will keep your microwaved blender bottles fresh and prevent buildup.
Storing Blender Bottles After Microwaving
Proper storage is also important after microwaving your blender bottle to maximize lifespan:
- Make sure bottles are completely dry before sealing lids
- Store away from heat sources like stoves or dishwashers
- Avoid leaving bottles in cars long-term where temperatures fluctuate
- Prevent exposure to UV light which can degrade plastic
- Keep lids loosely sealed if storing powders or liquids inside
- Replace bottles showing signs of clouding, cracking, or warping
With the right care and storage, a high-quality microwave-safe blender bottle can last through many uses. But it’s important not to overlook proper maintenance.
Blender Bottle Microwave Safety Tips

- Double check for microwave-safe markings – Never microwave a bottle without verifying it’s microwave-safe
- Remove all metal parts – Blender balls, whisks, and lids must be taken out
- Use lower power levels – Microwave at 50% power or less to prevent hot spots
- Heat in short bursts – Microwave in 30 second increments, stirring in between
- Allow to rest before opening – Let bottle cool and contents settle before handling
- Inspect for damage – Check for warping, cracking, melting after microwaving
- Clean thoroughly after use – Wash with bottle brush and sanitizing agent
